qemuAdds support for braille displays using brlttyEnables support for Linux's Async IOEnable alsa output for sound emulationSupport ISOs / -cdrom directives vis HTTP or HTTPS.Enables firmware device tree supportEnables GlusterFS cluster fileystem via
sys-cluster/glusterfsUse gtk-2 instead of gtk-3Enable direct iSCSI support via
net-libs/libiscsi instead of indirectly via the Linux
block layer that sys-block/open-iscsi does.Enable the ncurses-based consoleEnable NFS supportEnable NUMA supportPin the versions of BIOS firmware to the version included in the upstream release.
This is needed to sanely support migration/suspend/resume/snapshotting/etc... of instances.
When the blobs are different, random corruption/bugs/crashes/etc... may be observed.Enable pulseaudio output for sound emulationEnable rados block device backend support, see http://ceph.newdream.net/wiki/QEMU-RBDEnable the SDL-based consoleUse libsdl2 instead of libsdlEnable Spice protocol support via app-emulation/spiceEnable SSH based block device support via net-libs/libssh2Builds the Software MMU (system) targets as static binariesBuild the User targets as static binariesEnables both 'static-softmmu' and 'static-user'Enable support for snappy compressionEnable SystemTAP/DTrace tracingEnable the TCG Interpreter which can speed up or slowdown workloads depending on the host and guest CPUs being emulated. In the future it will be a runtime option but for now its compile time.Enable TLS support for the VNC console server.
For 1.4 and newer this also enables WebSocket support.
For 2.0 through 2.3 also enables disk quorum support.Enable jpeg image support for the VNC console serverEnable png image support for the VNC console serverEnable USB passthrough via dev-libs/libusbUse sys-apps/usbredir to redirect USB devices to another machine over TCPEnable UUID support in the vdi block driverEnable VDE-based networkingEnable accelerated networking using vhost-net, see http://www.linux-kvm.org/page/VhostNetEnable VirtFS via virtio-9p-pci / fsdev. See http://wiki.qemu.org/Documentation/9psetupEnable terminal support (x11-libs/vte) in the GTK+ interfaceAdd support for getting and setting POSIX extended attributes, through
sys-apps/attr. Requisite for the virtfs backend.
Enables support for Xen backendsSupport xfsctl() notification and syncing for XFS backed
virtual disks.
